COMBINATION-FAUCET.

SPEGIFICATION formingpart of Letters Patent No. 693,315, dated February 11, 1902.

Application tiled April 23, 1900.

To @ZZ whom t may concern.:

Be it known that I, GUs'rivE A. SODERLUND, of Somerville, in the county of Middlesex and State of Massachusetts, have invented a newV 1o in which the arrangement is suchthat by the turning of a single hand wheel orlever either hot or cold water or water of an intermediate temperature may be made to iiow from the mouth of the faucet; and it consists in combining with the hot and cold Water pipe at their junctions with the faucet cam-operated valves and in connected mechanism for perfecting the operation of the parts.

The object is to so improve the construetion of this class of faucets that there s hall be no danger of disarrangement of the parts or failure to operate.

The object I attain bythe mechanism shown in the accompanying drawings, in which- Figure l shows one of my faucets in front elevation. Fig. 2 is avieW showing in plan parts that relate to an indicating device. Fig. 3 is a vertical section of the entire device. Fig. 4 is a horizontal section of the same.

In the drawings I have indicated the coldwater pipe by C and thehot-water pipe by H and the discharge by D. The discharge-nozzle D leads from the receiving-chamber A, which is centrally located, as shown in Figs. 3 and 4. The valves C and II have stems C2 C*f4 and H2 H3 and are each provided with closing springs. (See C4 and H4.) The stems C2 C3 and H2 Hs extend both sides of their respective valves. Thus the parts C2and H2 ex-y tend from the faces of the valves through the guides B B into the central or receivin g chamber A, and the parts H3 Cs4 extend through the springs H4 C4 and have square ends which fit loosely into recesses formed in the end plugs D and D', so that the valves cannot turn on their axes. The hot and cold water valves H and C are operated by the following-described devce: A bisymmetrical cam L,Figs. 3 and 4, is rigidly attached to the shaft S. This shaft S passes up through the stufling- Serial No. 14,042. (No model.)

box S and is provided with a hand-wheel K and has attached to it a pointer P, the end of which traverses over the graduated plate G, which is divided into sectors marked Shut, Hot,. Warm, Cold, Shut. (See Fig. 2.) The lower end ofthe valve-shaft S has a stop-arm N, which is adapted to engage with the fixed stops A2 A2, and thus prevent the cam L from being turned too tar either to the right or left.

S2 is a spring which is placed'between the disk S3 on' the valve-shaft S and the upper wall of the chamber'A,-so as to bring a certain amount ot' friction upon the shaft S, and thus hold it in any position in which it is left by the user.

My combination-faucet works as follows: When the cam L occupies the position shown in Fig. 4, the pointer P stands at Shut at the left, as shown in Fig. 2, and the points T T' are opposite the ends of the valve-stems H2 C2. To open the hot-water valve H, the

'handle K is turned from the left toward the right, bringing the pointer P onto the division Hot This will turn the cam L, so that the. part T2 will act on vthe valve H and open it, thus letting on the hot water, the point T3 being opposite the valve-stem C2. Now by turning' the cam L more to the right the pointer P will occupy the division Warm, and the points T7 T of the cam will be in contact with the valve-stems H2 C2 and force both valves open, letting on hot and cold water, which, mixing, gives Warm Now a further turning ofthe cam will bring the point T4 against the valve-stem C2, and thus allows it to remain open; but the point TS will be opposite the stem H2 of the hotwater valve H', and thus allow it to close, so that only cold water can flow. A continued rotation of the cam will complete its full half-turn, and the pointer P will stand at Shut7 on the right hand. The point T' of the cam will be opposite the stem H2 and the point T will be opposite the stem C-that is, both valves will be closed.

I claiml. In a combination-faucet; a central receiving-chamber having a discharge-nozzle,

and` valvular connections with thehot and roo anni.;

cold Water supply pipes; hot and cold Water valve-chambers provided with valve-seats, adapted to receive valves, which in opening move away from the said central receivingchamber, each of said chambers having two openings beside the valve-opening, that is, an inlet water-supply, and a screw-plugged opening large enongh'to admit of the placing and adjusting the Water-valve; and a bisynimetrical cam adapted to operate said valves, substantially as and for the purpose set forth.

2. In a combination-faucet; a central receiving-chamber having a discharge-nozzle, and valvular connections with the hot and cold Water supply pipes; hot and cold Water valve-chambers provided with valve-seats, adapted to receive valves, which in opening move away from the said central receivingchamber, said valve-chambers having screwplugged openings large enough to receive, from the exterior, the hot and cold Water valves; said hot and cold Water valves; having stems extending in both directions from the valve and adapted to act as guides, their outer ends being squared and adapted to fit loosely in recesses made in the end plugs; said end plugs; and a bisymmetrical cam adapted to operate said valves, substantially as and for the purpose set forth.

3. In a combinationffaueet a central re ceiVing-charnber having a discharge-nozzle and valvular connection with hot and cold water pipes; valves adapted to open and close said hot and cold water pipes; a cam adapted to operate said valves, mechanism for operating said cam, and a spring adapted to frictionallyhold said cam in any position in which it is set, substantially as and for the purpose set forth.

In testimony whereof:` I have signed my name to this specification, in the presence of two subscribing Witnesses, on this 29th day of March, A. D. 1900.
